To dill whom it' may coiweria Be itl' znofwn that I GEOR E M, Sonn LER,a

specification,

' i citizen of the United States, re sidingat In-" diana'polia'inthecounty of, Marion and State ,1 of Indiana, have-invented certain new anduse-' ful Improvements in Carbureters for Hydro-, carbon Moto'rs,- ofwhich the following a In thejcon's'truction ofiautomobilesofthegas-engine type. a carbureter isan essential element; and'the object ofmy present' in-vention is to. provide an efficient carbureter of g thetype shown in my Patent No. 711,005-

N which is exceedingly compact and the parts t each other in order toadapt the apparatus for of whichmay berearranged with relation to use indiifere'nttypes of machines.

A' furtherobjectfof my invention is to pro vide meansforautomaticallyvarying the proportions and the characterlof the mixtureproduced and to provide such improvements in details of construction asare hereinafter pointed out.

' K'lhe accompanying drawings illustrate my invention.v

' In the drawings, indicates a semisphe'rical shell or body havingformedtherein-an L-shaped passage 11, which terminates at its upper end in atubular projection. projectir'ig above the 'o enupper end of p the mainshell,

. while theother end, terminates'in a face 12% the side ofthe mainshell. Projected upward through the body of she'lllO and into the L-shaped passage 11 is a fuel discharge'nozzle 13-,

which communicateswith theinterio'r of body lO and'within which isarranged a suitable nee-' dle-valve 14. E Secured inthebottomf of casing10 isan inlet-plu'g'1 5, having a central passage 16, which'communicateswith the interior'of "shell 10 and which is provided at its lower endwith avalve-seat 17, in which thevaive18' can be seated; v y The stemofva'lve glgisprojected downward'throughi passage=17and attached {to alever 19, pivoted within casingld and communicates, through passage 22,with the lower endof the plug.

e device, showing the air ini "plug 15, over groove'21, is collar 23,carry- 3 ing an inlet-pipe 24,,to which a suitable'fu'elsupply pipe maybe attached. The collar 23 may be's wung around plug to point in anyjdirection; necessaryftoconnectwith proper supply-pipe and is clampedtightly anydesired position against a suitable collar25 by means of acap 26, secured upon the outer endof .plug 15 and thusforming] acommunication between passage 22"and the-passage 16.

. The upper end of the main casing 10 1s closed 3 1 hya suitable:annular cap 27, which upon its upper face is'provided'with a face 28,corresponding 'insizeandarrangement of ,boltopenings with the'face 12,and this cap is of such-shapenand dimensions that the tubular end ofpassage 11 rises just to the top of? the cap and fits thereina Adaptedto fit'either oneof faces .12 or 28 is an air-inlet 29, which haspivoted therein a check'-pla-te'30, whichnormally lies across the,

passage 29', with its freeend against a suitablestop-pin 31. Plate 30 iscarried by a Shaft 32,,which is provided at one end with a crank33,,conne'cted to' a plunger 34, the end ofwhich lies within a casing 35and abuts against a'suitablespring 36. Also adapted to :be secured'toeither of faces 12' and 28 is a,

throttle-valve structure 37, within which is mounted a valve-plate38,0perated by a suitable valvearm 39. .Valve structure'37 is providedwith an eduction-passage 40, which'is offa size and shape to takeanordinary-stand ard pipe, and, if desired, the val've-platev38p may bemade of such shape as to close such an opening. I prefer, however,."toplace a partialdiaphragm 41 immediately adjacent the valve-plate,between it and the educti0n-.

passage 40, and'form therewith an eduction opening having a -shapedlower side. As-a consequence of this construction an appreciable openingmay be produced immediately of the usual circular shape. v

'.'.The device described is exceedingly compact, and in operation thethrottle' valve structure and the. inlet structure may be attached vuponopening the throttle-valve; but-this r to the maincasing in'eitherpositiomwhich evermay be most convenient-foruse in connection with theparticular cooperating mech-' anism, and'thefuel-inlet collar 23 maybealso swung to any'desired point. Under ordinary speeds the suctionof theengine will be such that check-plate 30 will remain across theinlet-passage; but in case of high speeds the plate 30 will yield,depending upon the adjustment of spring 36, and thus increase thesize'of the air-inlet, so that the mixture produced will be less rich.

I claim as my invention-- 1. A carbureter consisting of, a main casinghaving an air-passage therethrough with an induction-opening and aneduction-opening, an air-inlet structure, a throttle-valve structure,and rneans for securing either of said structures to either theinduction or eduction openings.

2. Acarbureter consisting of, a main casing having an air-passagetherethrough with an induction-opening and an eduction-opening, and anair-inlet structure provided with a yielding check-plate normallyobstructing the passage therethrough.

3, A carbureter consisting of, a main casing having an air-passagetherethrough with an induction-opening and an eduction-opening, anair-inlet structure provided with a yielding check-plate normallyobstructing the passage therethrough, a throttle-valve structure, andmeans for securing the inlet structure and the throttle-valve structureto either the induction or eduction openings.

4-. The combination, with a carbureter, of a throttle-valve structureconsisting of an eduction-passage having .a V-shaped diaphragm therein,and a swinging valve-plate arranged adjacent said diaphragm,substantially as set forth.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 20th day of October, A. D. .1903.
